Dig Deeper with Lance MacNevin, Director of Engineering with Plastics Pipe Institute — New PPI Model Specification for Piping Materials for Geothermal Systems

In May 2023, The Plastics Pipe Institute (PPI) published a new Model Specification for “Plastic Piping Materials for Ground Source Geothermal Applications”. PPI MS-7 applies to plastic piping materials for open- and closed-loop, horizontal and vertical, direct-buried, and submerged water-based ground-source geothermal heat exchange systems. It includes detailed specifications for four plastic piping materials which have been proven for use in ground source heat exchange systems: HDPE, PE-RT, PEX, and PP (PP-R & PP-RCT). The model specification provides language related to pipe and tubing materials, fittings, and joining procedures. Installation and pressure testing recommendations are also provided. This publication is intended for use as a guide to support designers and specifiers of ground source geothermal heat exchange systems, and this presentation will explain the contents of PPI MS-7 and how it can be used to save time when specifying ground source piping systems, while ensuring the requirements are current and correct.
